Rotate the folded dough 90 degrees to your right. Spread the dough like a rectangle again and repeat the fold. You have to make at least four letter folds, five if you can. If the dough resists too much, stop folding and let the dough rest for at least 20 minutes in the fridge before resuming. Always rotate in the same way. Make the folds as quickly as possible while the dough is cold. Once the dough starts to heat up, the butter might start leaking. Cover the dough with saran wrap and let it rest in the fridge for at least an hour. In the meantime, make the applesauce.
